Both Cummins and International have developed exhaust gas recirculation (EGR) technology to meet the new standards while Cat has opted to develop engines using advanced combustion emission reduction technology (ACERT).
Company executives emphasized how International has engineered upgrades into its trucks beyond what was necessary to accommodate new compliance technologies. They include:
